US Navy funds MIT robotic JELLYFISH that can catch fish

It might not have the speed of using a net or the finesse of a rod and line, but a military funded robot made out of jelly could give fishermen some competition. Engineers at the Massachusetts Institute of Technology have created a swimming robot out of gel that can capture a live fish in its'tentacles'. The robot, which looks remarkably similar to a jellyfish and was partly funded by the US Office of Naval Research, can move by pumping water through their body. The robot (pictured) is made from a jelly like material called hydrogel, which gives it a soft rubbery texture and makes it almost see-through. They can also rapidly curl and uncurl their arms by inflating them with water, giving them a fast and firm grip.
